Soundproof Walls {Structure of Noise Barrier}

The present invention relates to a sound insulation wall mainly installed on a roadside around a road boundary, and in particular, it is possible to change a conventional sound insulation wall treatment exterior that was treated as a monotonous wall surface for a soundproof wall installation into an environmentally friendly structure, but with a special finishing material or auxiliary material. It can be simply installed without a device, and it is possible to make a simple replacement construction for existing sound insulation and sound insulation walls.

Noise barriers installed between noise areas such as residential areas, roads, and construction sites generally use sound absorbing walls and sound barriers to block noise.

The sound absorbing wall uses a separate sound absorbing material for absorbing noise, and the sound insulating wall is installed along the direction of the noise to block the movement of the noise, and thus does not require a separate sound absorbing material. The soundproof wall is constructed so that noise hits the soundproof wall and radiates around the noise source, so there is no need to install a separate sound absorbing material. Therefore, it is cheaper than the sound absorbing wall and is easy to install and install according to the surrounding environment of the noise source. .

In general, the sound insulation wall is installed by placing the H-shaped steel on the upper portion of the concrete retaining wall at predetermined intervals and inserting the sound insulation concrete block therebetween.

1 illustrates a conventional sound insulation wall construction structure. The construction of the sound insulation wall 10 includes a support frame 40 having a coupling surface 30 bidirectionally symmetrical, such as an H beam beam, along a concrete retaining wall 20 structure. Standing on the concrete retaining wall (20), along the coupling surface 30 formed on the support frame 40 is constructed by inserting the support frame 40 to the axis of the sound-proof wall 10 on the panel.

The sound insulation wall 10 of the sheet used in the construction of the sound insulation wall is panel-shaped in its entire shape and manufactured to have a thickness enough to be easily fitted along the coupling surface 30 of the support frame 40. Along the 40 to install from the bottom to the top.

On the other hand, in order to enhance the sound insulation effect in the construction of the sound insulation wall is also applied to the design to effectively emit the noise emitted from the noise source by forming the surface of the sound insulation wall in the shape of unevenness.

FIG. 2 is a structure in which the surface shape of the sound insulation wall 10 is processed into a concave-convex shape so that the noise radiated from the noise source 50 is intensively refracted so as to be directed in a specific direction instead of being fed back along the original path, thereby enhancing the noise shielding effect. For example, if the source of the noise source 50 is a passenger vehicle, if the noise generated from the vehicle is directly fed back to the same position, the noise felt while riding the vehicle becomes too large and does not consider the noise reduction effect on the noise source side. As a result, it may be unsuitable for the road facility, but as shown in FIG. 2, the noise hits the unevenness 60 portion first on the surface of the sound insulation wall 10, and then the front surface of the unevenness 60 so that the refractive direction thereof is directed upward. Given the intended angle of inclination, the noise shielding effect can be provided to the noise source.

As compared with the sound absorbing wall, the conventional sound insulation wall has a relatively simple structure and is easy to install, and various sizes and field construction conditions are good. However, the surface is visually coarse using light and non-metallic materials, resulting in a beautiful construction appearance. Couldn't get it. Recently, various sound insulation walls have been proposed to enhance the aesthetics and affinity of the surface, or to diversify the colors to give a visual aesthetic, but the overall shape itself is impossible to be modified, so that the design is improved and monotonous. There was a limit to improving aesthetics.

In addition, a light metal or a non-metallic material having a certain strength is used as a main material of the sound insulation wall, and its shape is exposed as it is. In order to make up for these drawbacks, some environmentally friendly management has been applied to plant vegetation around the location where the sound insulation walls are installed so that the stems climb up the sound insulation walls to cover the surface of the sound insulation walls. However, this method also completely compensates for the shortcomings of sound insulation walls classified as non-environmental facilities because they can only be used for a limited time during the season when vegetation growth is active, and because they radiate vegetation on land and can harm urban landscape. It didn't grow in the way it could.

Accordingly, an object of the present invention is to provide an environmentally friendly sound insulation wall that can be suitably used as an exposure facility or a building facility on a road.

Another object of the present invention is to provide a sound insulation wall that can be easily and simply installed around the sound insulation wall support frame.

Another object of the present invention is to provide a sound insulation wall that can be replaced in the existing support frame intact.

Another object of the present invention is to provide a soundproof wall that can be installed without a separate fastening or connecting part when applying the gravity-type structure.

Features of the present invention for achieving this object, in the sound insulation wall to be fitted along the coupling surface of the support frame having a coupling surface in both directions to assemble the sound insulating wall at a predetermined interval on the concrete retaining wall structure,

The sound insulation wall,

A sound insulation wall body assembled along a positioned support frame, the upper part of which is emptied into the vegetation soil space, and the lower part of which is blocked;

It is formed on both ends of the sound insulation wall body, characterized in that consisting of a coupling portion coupled along the coupling surface of the support frame.

In this way, if the soundproof wall installed around the road is environmentally friendly for noise prevention purposes, it is possible to keep the urban landscape and aesthetics beautiful without the noise shielding effect of the soundproof wall, and construct the soundproof wall as an environmental management facility without any reinvestment. It will be possible to construct a simple, easy to replace the existing construction of the sound insulation wall, and to provide a visually diversified sound insulation wall.

The sound insulating wall 70 according to the present invention is a coupling surface of the support frame 73 having coupling surfaces 72a and 72b that can be assembled to the sound insulation wall 70 at predetermined intervals on top of the concrete retaining wall 71 structure. It is designed to fit along 72a and 72b.

Specifically, the sound insulation wall body 75 is assembled along the positioned support frame 73 and the upper part is emptied into the vegetation soil space 74, and the lower part is formed at both ends of the sound insulation wall body 75 and is supported. The coupling portion 76 is coupled along the coupling surfaces 72a and 72b of the frame 73.

Optionally, as shown in FIG. 4, the sound insulation wall main body 75 may be formed in a left-right symmetrical triangle shape having an upper surface area wider than a lower surface area, narrowing toward the lower side, and having inclined slope surfaces 77a and 77b symmetrically from side to side. have.

In addition, the sound insulation wall main body 75, as shown in Figure 5 (b), when the direction of the noise source in the front, the front portion is made out of left and right asymmetric triangular shape is exposed outside, the front portion is inclined gradient surface It can form in triangular shape through 77a.

Optionally, the engaging portion 76 is composed of a protruding end 78 to be fitted in close contact with the space of the engaging surfaces 72a, 72b of the support frame 73.

Effects of the present invention configured as described above are as follows.

Figure 3 shows the construction state of the sound insulation wall 70 through the sound insulation wall body 75 according to the present invention. Since the sound insulation wall body 75 of the sheet according to the present invention has a certain weight, it is gravity-coupled from the top to the bottom along the groove space on the engaging surfaces 72a and 72b of the support frame 73.

For this coupling, the shape of the coupling portion 76 formed on the sound insulation wall body 75 is determined in consideration of the shape of the coupling surfaces 72a and 72b of the support frame 73 in advance.

That is, as shown in FIG. 3, when the engaging surfaces 72a and 72b of the support frame 73 for coupling the sound insulation wall main body 75 are recessed inwardly, the grooves of the support frame 73 may be inserted into and inserted into the grooves of the support frame 73. The coupling portion 76 formed on both side ends of the sound insulation wall body 75 can be easily formed by forming the protruding end 78. In the construction of coupling the sound insulation wall main body 75 to the support frame 73, the assembly is completed by gravity without a separate fastening device or an auxiliary device, and several sound insulation wall main bodies 75 are stacked and stacked in the same order as the former. When raised, the sound insulation wall 70 is completed.

An important feature of the sound insulation wall according to the present invention is that the upper surface of the sound insulation wall body 75 is provided with a vegetation soil space 74 which is an empty space so that vegetation can grow there.

The shape of the sound insulation wall main body 75 suitable for this structure is a symmetrical triangular shape in which the upper surface area is wider than the lower surface area and narrows toward the lower side, as shown in FIGS. It is left and right asymmetrical triangular shape with the front sloped slope 77a exposed outward and the backside not being exposed. Here, the role of the front slope inclined surface 77a serves to refract the direction of the noise radiated from the noise source through the slope gradient 77a while forming the upper surface to the vegetation soil space 74.
